Problems solved by technology
[0002] The driving device of the existing electric vehicle is a single motor, including a stator and a rotor. A silicon steel sheet and a permanent magnet are installed on the stator or rotor, and a winding coil is arranged on the silicon steel sheet. After being energized, an electromagnetic field is generated, and the interaction between the magnetic field and the magnetic field It is difficult for this kind of electric vehicle motor to meet the needs of starting and climbing; there are also electric vehicle motors with deceleration mechanisms to meet the needs of starting and climbing, but it still cannot meet the needs of the market and customers. The proposed requirement that electric vehicles should be able to stop and start on slopes

Embodiment Construction
[0021] A specific embodiment is described in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 as follows: an electric vehicle driving device with a centrifugal clutch and an overrunning clutch with flexible coupling, including a hub, a left cover plate, a right Cover plate, center shaft, motor, centrifugal clutch and overrunning clutch. The motor adopts an external rotor high-speed motor. The stator is fixed between the right section of the central shaft and the inner wall of the rotor. There is a silicon steel sheet on the stator, and a winding coil on the silicon steel sheet, which is connected to the electronic controller. The rotor is mounted on the Between the right section of the inner wall of the wheel hub and the right section of the central shaft, its right end is connected with the star wheel of the overrunning clutch, and can rotate around the central shaft. There is a permanent magnet on the inner wall of the rotor. The centrifugal clutch adopts a...
